Thanks to all that have offered suggestions. Although I haven't got the
interface working yet, I've pretty much narrowed it down to a bad baud rate
clock on my RS-422 board. I measured it with a little timing routine I wrote
and found my baud rate to be out of spec by 52% at a baud rate of 38.4kbs. I
can't blame the decks for not responding to that kind of error. Right now I'm
looking for a local store where I can buy a new crystal for the board.
I also dicovered that the board I have is really RS-423 not RS-422 although the
two standards are compatible. My testing also leads me to believe that the
UVW-1800 interface is infact RS-423 also and not 422 as documented. Not that
this matters any.
